LED lighting development is unstoppable
2014/11/22
Standard issue is one of the topics of most concern LED lighting industry.Architectural Design and Research Institute of Tsinghua University Ltd., the vice president of the Building Environment and Energy Conservation Chinese Academy of Building Research, CSA application Promotion Committee Zhao Jianping, director of interpretation of the new "architectural lighting design standards" (GB50034-2013) regarding LED lighting terms.
According to reports, about lighting design standards are another update on LED lighting terms. In addition to "architectural lighting design standards" (GB50034-2013), the "city road lighting design standards" (CJJ45), "stadium lighting design and testing standards" (JGJ153) is revising them, "LED indoor lighting applications technical requirements" , "LED city road lighting applications technical requirements" has completed its review. Zhao Jianping frankly, the reason for the previous lighting designers not "bold" use of LED lamps, because there is no standard.
Thus, along with a number of lighting design criteria for the introduction of standardized LED products, LED lighting applications in various places will be fully rolled out.
Zhao Jianping said the new "architectural lighting design standards" (GB50034-2013) in the evaluation include: number four lighting, lighting quality, energy-saving lighting, the principle is to make lighting products are safe, comfortable, energy saving and environmental protection.
Zhao Jianping emphasis on the new mandatory standards GB50034 standard, some performance requirements even higher than Europe and America.
It is worth noting that, in addition to optical efficiency problems the industry has been concerned about the new standard highlighted several important indicators of lighting comfort. For example, the choice of color tolerance between similar sources should be less than 5SDCM; CRI of not less than 80, R9 should be greater than zero. Especially in long-term or staying room or place, the color temperature is not higher than 4000K; LED chromaticity coordinates of the deviation from the initial value of the lifetime should be more than 0.007; LED lamp color coordinates the deviation not more than 0.004 different directions and so on.
As a bridge project with the owners, between engineering and product designers in lighting design in compliance with the standard determines the selection of lamps, and this issue is LED lighting suppliers are most concerned about. Designers will choose what kind of lighting?
Zhao Jianping stressed, LED lighting companies tend to offer only light efficiency and light distribution curve, while ignoring the mandatory standards specified in the new standard, the designers did several indicators above, it can not be calculated.
In addition to corporate provided incomplete product parameters, the current LED lighting products have not been able to form a standardized, product classification is not conducive to the designer's choice, as well as uneven product quality and other issues still restricting the penetration of LED lighting to the interior process.
Although the use of LED lighting designer for interior lighting is still very cautious, but Zhao Jianping still believe, LED products will be all over in every corner of lighting, semiconductor lighting in the lighting field development is unstoppable, semiconductor lighting energy saving play its enormous potential.
